Google Apps is now G Suite. Same service, new name. More about the name change.

Google Sync End of Life

Starting January 30, 2013, you aren't able to set up new devices using Google Sync. Existing Google Sync connections continue to work and Google Sync continues to be fully supported for G Suite, Drive for Work, and Government and Education users.

Additionally, three other legacy syncing services have also reached their end of life and are no longer supported by Google for any users: Google Calendar Sync, Google Sync for Nokia S60, and SyncML.

Google Sync was designed to allow access to Gmail, Google Calendar, and Contacts via the Microsoft® Exchange ActiveSync® protocol. With the recent launch of CardDAV, Google now offers similar access via IMAP, CalDAV, and CardDAV.

What do I need to do if I’m already using Google Sync?

Nothing. Existing users can continue to use Google Sync on their current devices.
